It is critical to control the alpha amylase activity in malt as this determines the outcome of the mashing at breweries and distilleries. Malt houses often provide malt with different enzyme activities that enable different brewing results. Phadebas Amylase Test has been used for many years, both at malt suppliers and breweries, to get a precise determination of the alpha amylase activity. Phadebas was listed as a harmonised method for α-amylase determination in malt in Analytica by the European Brewing Convention* already back in 1987.
